Embodiment

[0019] Please refer to the accompanying drawings, as the drainage container 1 of the thoracentesis negative pressure drainage device provided by the present invention is made of the first and second spherical caps 11, 12 whose materials are polyvinyl chloride, what is said here The concepts of the first and second spherical caps 11 and 12 are based on their shapes, so they can also be referred to as the first hemisphere and the second hemisphere. It can be known from the shapes shown in the figure that the first and second spherical caps 11 and 12 are like a pair of interlocking bowls. The first spherical cap 11 is made of transparent rigid polyvinyl chloride, and the second spherical cap 12 is made of elastic polyvinyl chloride. The cooperation of the first and second spherical caps 11 and 12 can play the effect of a "skin tiger" commonly used in the sanitary ware industry, such as for dredging the sewer, and the negative pressure effect is very ideal.

Abstract

The invention relates to a drainage tube for a thoracocentesis negative pressure drainage device, which belongs to the technical field of medical appliances. The thoracocentesis negative pressure drainage device comprises a drainage container and a spring arranged in the drainage container, the drainage tube comprises a tube body, wherein drainage holes are arranged at intervals on the tube wall at one end of the tube body, and all drainage holes are communicated with a tube cavity of the tube body. The invention has the advantages that because one end of the tube body is provided with the drainage holes, the cigarette holder type drainage effect can be realized for shortening the drainage time, and the drainage tube is provided with the tube cavity with the advantages that a puncture cutter can be matched and connected with the tube body, the operation can be simplified, and the tube body blockage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a drainage tube for a thoracentesis negative pressure drainage device. Background technique [0002] The thoracentesis negative pressure drainage device is usually equipped with a drainage tube, for example, the multifunctional thoracentesis negative pressure drainage device recommended by the Chinese utility model patent authorization announcement number CN2782100Y, the thoracentesis negative pressure drainage device introduced by CN2848232Y and the medical chest cavity disclosed by CN201064579Y Negative pressure drainage devices and the like are all equipped with drainage tubes without exception. Specifically, one end of the drainage tube is connected with the drainage container and communicated with the drainage container, and a puncture needle is arranged at the other end. When in use, after the puncture is aimed at the patient's thoracentesis, one end ...
